We're starting to look into a FCP7 workflow, as some of our clients use it over FCP6. So, in order to do this, we've cloned our partition (somewhat unnecessary, I know), and then clean installed the OS & FCP on it. After Effects is installed on the FCP6 partition, and I am trying to figure out if it is possible to get it to run on both partitions, so that I don't have to keep rebooting to the other partition when I need AE for a job. I know it installs some files into the home dir, but I'm trying to see if it's possible. I've Googled and searched this forum, but haven't really found anything saying one way or the other about this.

And I'd use Premiere, but our clients all tend to need FCP, unfortunately.

One detail of the single-user retail license for After Effects is that you can activate twice. This is intended for you to have one instnace installed and activated on your desktop computer and another on your laptop, but there's no reason that you couldn't use this same feature to install and activate on both of your partitions.

Why I did what? FCP7 projects aren't backwards useable, and our other two edit machines use 6 (one is non-Intel, so it can't even go to FCP7). So, FCP7 needed to be isolated. Plus there was an upgrade to Snow Leopard on that partition.

Ah. I didn't realize that FCP 6 couldn't exist on the same system as FCP 7. I'm used to having CS3, CS4, and CS5 versions of our software installed (and even running) simultaneously on the same system.
